MAX6965AEE+

LED Driver IC Overview

The MAX6965AEE+ is a 9-output LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 2 V to 3.6 V and draws a maximum supply current of 110 µA. The device features a 400 kHz switching frequency and supports a 400 kbps I²C-compatible interface. Each output channel provides up to 50 mA of drive current. It is housed in a 16-pin QSOP package and functions within an operating temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Provides nine individually addressable LED outputs with linear intensity control capabilities.
• Integrates a high-frequency switching regulator to minimize external component count.
• Supports serial communication via a standard two-wire interface for data input.

LED Driver IC Applications

• LED segment display drivers
• Backlight control systems
• Portable electronic devices

LED Driver IC Procurement Notes

Verify the specific suffix 'E' indicates the industrial temperature grade (-40°C to +125°C) and the '+' denotes lead-free compliance. Confirm the QSOP-16 package dimensions against your PCB footprint requirements. Check current availability status as distribution may be limited or subject to factory order constraints.

LED Driver IC Selection Notes

Select this component when a compact solution for driving multiple LED segments is required without complex external circuitry. Ensure the system power budget accommodates the 110 µA quiescent current. Verify that the 50 mA per channel output capability meets the forward current requirements of the selected LEDs.

LED Driver IC Part Context

This part belongs to the MAX6965 series of LED display drivers designed for space-constrained applications. It replaces discrete transistor arrays or simpler shift registers by integrating regulation, decoding, and drive circuits into a single monolithic IC.

LED Driver IC Replacement Considerations

Consult official documentation for direct pin-to-pin replacements within the same family. Generic substitutes may lack the integrated switching regulator or specific intensity control features.
